How to cook a frozen beef roast in the oven?

For cooking a frozen beef roast in the oven, you first need a large baking pan with elevated sides. An instant pot would work as well. Never use a slow cooker for cooking frozen meat as it prevents the meat from reaching a safe internal temperature of 140F.

If you have no other option, you can use a slow cooker but make sure you cook the roast for about 8-10 hours. After pouring the soup, broth, sauce, herbs, and seasoning over your roast, slide the baking tray into the preheated oven.

The baking time and temperature vary with the size of your roast. Most recipes would call for baking your roast at 375F for 2-5 hours if it weighs 3-6 lbs. If the roast weighs 2-3 lbs, a baking time of 2-3 hours will suffice.

To check the doneness of the roast, insert a thermometer in the thickest part of the roast. Depending upon how you like your roast, the thermometer should read as given in the table below.

Rare 120°F
Medium rare 130-135°F
Perfectly medium 135-145°F
Medium well 145-155°F
Well 155°F or higher
